Definitions

  • the present invention relates to new intermediates of structured 19-nor steroid and substituted in position 2 as well as their preparation process.
  • French patents 1,476,572 and Swiss patents 473,106 were known to contain 19-nor products comprising an acetyl radical or a 1-hydroxy ethyl radical in the 17 ⁇ position. However, the products of the prior art do not include any substitution in position 2.
  • the subject of the invention is the products of formula Ii: in the form of 20R or 20S isomers or of their mixture, formula in which R 1 and R 2 identical or different represent a hydrogen atom, an alkyl radical containing from 1 to 4 carbon atoms or an alkenyl or alkynyl radical containing from 2 to 6 carbon atoms, it being understood that only one of the substituents R 1 and R 2 can represent a hydrogen atom, or else R 1 and R 2 together form a cycloalkyl radical containing 3 to 8 carbon atoms; R 3 represents an alkyl radical containing from 2 to 4 carbon atoms; OD representing an ether group.
  • R 1 or R 2 represents an alkyl radical, it is preferably a methyl or ethyl radical.
  • R 1 or R 2 represents an alkenyl radical, it is preferably an allyl radical.
  • R 1 or R 2 represents an alkynyl radical, it is preferably the 2-propynyl radical.
  • R 1 or R 2 together form a cycloalkyl radical, it is preferably the cyclopropyl, cyclobutyl, cyclopentyl or cyclohexyl radical.
  • the invention particularly relates to the products of formula li as defined above, for which R 3 represents an ethyl radical as well as those for which R 1 and R 2 each represent a methyl radical.
  • a more specific subject of the invention is (2'R, S, 20R, S) 2,2-dimethyl 13-ethyl 20- / 2 '- (tetrahydropyrannyl) oxy / 18,19-dinor pregn-4- then 3-one.
  • the subject of the invention is also a process for preparing the products of formula Ii, characterized in that a compound of formula II is condensed, by reaction of WITTIG: in which K and K ′ represent a ketone group blocked in the form of a ketal and R 3 represents an alkyl radical containing from 2 to 4 carbon atoms, with a triphenyl ethyl phosphonium halide of formula III: in which Hal represents a halogen atom, in the presence of a strong base, to obtain a compound of formula IV: in the form of a mixture of cis and trans isomers, which are separated, if desired, into each of the isomers, then subject either each of the isomers of formula IV, or their mixture, to the action of an agent d hydroboration, then to that of an oxidizing agent in an alkaline medium and finally to that of a decetalization agent and to that of a cyclization agent, to obtain a compound of formula V: in the form of 20R
  • the gem-dimethylation reaction is advantageously carried out in an aprotic solvent such as, for example, tetrahydrofuran.
  • R 3 represents an alkyl radical containing from 2 to 4 carbon atoms
  • R ' 4 represents a hydrogen atom, a hydroxyl radical, an acyloxy radical containing from 1 to 18 carbon atoms or a radical: in which M represents a hydrogen atom, a sodium or potassium atom, and either R 1 and R 2 , which are identical or different, represent a hydrogen atom, an alkyl radical containing from 1 to 4 carbon atoms , or an alkenyl or alkynyl radical containing 2 to 6 carbon atoms, it being understood that only one of the substituents R 1 and R 2 can represent a hydrogen atom, or else R 1 and R 2 together form a cycloalkyl radical containing 3 to 8 carbon atoms.
  • the compounds of formula I have interesting pharmacological properties; they are in particular antagonists of aldosterone and increase the diuresis hydrosodée with conservation of organic potassium, while being devoid of side effects. It has been observed in particular that at the doses where the products exhibit an interesting anti-aldosterone activity, these do not show anti-androgenic activity nor antiestrogenic activity. They can therefore be used to combat high blood pressure and heart failure.
  • the salification of the phosphorus derivative is carried out with sodium or potassium hydroxide.
  • the products of formula II, used as starting materials for the process of the invention are generally known products and which can be prepared according to the processes described in French patent 1,490,590 and in Danish patent 136,115.

  • Example 2 3.4 g of the product obtained in Example 2 are dissolved in 68 cm 3 of methanol. The solution is heated to reflux with nitrogen bubbling for 15 minutes, then 840 mg of potassium acid carbonate and 8.4 cm 3 of water are added. Maintained at reflux under nitrogen bubbling for 30 minutes, cooled and added 1 cm 3 of acetic acid. It is concentrated under reduced pressure, diluted with water and extracted with methylene chloride. The organic phase is washed with water and dried. It is evaporated to dryness. 3.06 g of product are obtained which is purified by chromatography on silica (eluent: benzene-ethyl acetate 8-2). 3 g of the desired product are obtained, melting at 138 ° C. after recrystallization from aqueous ethanol.
